Image of M31 heralds the dawn of HSC's productivity

A stunning image of M31 captured by Subaru Telescope's Hyper Suprime-Cam (HSC) displays the fruits of international collaboration and technological sophistication aligned with cutting-edge science. In addition to providing ...

Aging stars provide a new cosmological yardstick

Despite a century of measurements, astronomers can't agree on the rate at which the universe is expanding. A technique that relies on measuring distances to a specific type of aging star in other galaxies—called the J-region ...

Do black holes help stars form?

(PhysOrg.com) -- The center of just about every galaxy is thought to host a black hole, some with masses of thousands of millions of Suns and consequently strong gravitational pulls that disrupt material around them. They ...

The JCMT celebrates 25 years on top of the world

The James Clerk Maxwell Telescope (JCMT) on Mauna Kea in Hawaii, is celebrating its 25th birthday this week. It first turned its dish to the heavens this week in 1987, and now, a quarter of a century later, the JCMT continues ...

Hubble eyes a loose spiral galaxy

(Phys.org)—The Hubble Space Telescope has spotted the spiral galaxy ESO 499-G37, seen here against a backdrop of distant galaxies, scattered with nearby stars.

The tell-tale signs of a galactic merger

The NASA/ESA Hubble Space Telescope has captured this striking view of spiral galaxy NGC 7714. This galaxy has drifted too close to another nearby galaxy and the dramatic interaction has twisted its spiral arms out of shape, ...

Wall Divides East and West Sides of Cosmic Metropolis

(PhysOrg.com) -- A new study unveils NGC 604, the largest region of star formation in the nearby galaxy M33, in its first deep, high-resolution view in X- rays. This composite image from Chandra X-ray Observatory data (colored ...

Most elliptical galaxies are 'like spirals'

(PhysOrg.com) -- The majority of 'elliptical' galaxies are not spherical but disc-shaped, resembling spiral galaxies such as our own Milky Way with the gas and dust removed, new observations suggest.

Hubble focuses on 'the great attractor'

(Phys.org)—A busy patch of space has been captured in this image from the NASA/ESA Hubble Space Telescope. Scattered with many nearby stars, the field also has numerous galaxies in the background.

Stars' clockwork motion captured in nearby galaxy

(Phys.org) —Using the sharp-eyed NASA Hubble Space Telescope, astronomers have for the first time precisely measured the rotation rate of a galaxy based on the clock-like movement of its stars.
